Introduction
0.1 Introduction to FprCEN/TS 19101

This document for the design of fibre-polymer composite structures, which was prepared in line with the

Eurocodes, is intended for use by designers, clients, manufacturers, constructors, relevant authorities (in

exercising their duties in accordance with national or international regulations), educators, software

developers, and committees drafting standards for related product, testing and execution standards.

NOTE 1 Some aspects of design are most appropriately specified by relevant authorities or, where not specified,

can be agreed on a project-specific basis between relevant parties such as designers and clients. The Eurocodes

identify such aspects making explicit reference to relevant authorities and relevant parties.

NOTE 2 Fibre-polymer composites are also commonly referred to as fibre-reinforced polymers (FRP) or as composites.

0.2 Verbal forms used in this Technical Specification

The verb “shall" expresses a requirement strictly to be followed and from which no deviation is permitted

in order to comply with the Eurocodes.

The verb “should” expresses a highly recommended choice or course of action. Subject to national

regulation and/or any relevant contractual provisions, alternative approaches could be used/adopted

where technically justified.

The verb “may" expresses a course of action permissible within the limits of the Eurocodes.

The verb “can" expresses possibility and capability; it is used for statements of fact and clarification of concepts.

0.3 National Annex to FprCEN/TS 19101

This Technical Specification gives values within notes indicating where national choices can be made.

Therefore, a national document implementing FprCEN/TS 19101 can have a National Annex containing

all Nationally Determined Parameters to be used for the assessment of buildings and civil engineering

works in the relevant country.

When not given in the National Annex, the national choice will be the default choice specified in the

relevant Technical Specification.
The national choice can be specified by a relevant authority.

When no choice is given in the Technical Specification, in the National Annex, or by a relevant authority,

the national choice can be agreed for a specific project by appropriate parties.
National choice is allowed in FprCEN/TS 19101 through the following clauses:
4.3.1.2(4), NOTE 2
4.4.6(1), NOTE 4.4.6(2), NOTE 4.4.6(3), NOTE
4.4.7.1(2), NOTE 4.4.7.1(3), NOTE 8.5(2), NOTE 4 10.3(1), NOTE 1
12.4.5.1(1), NOTE 1 D4.5(1), NOTE

National choice is allowed in FprCEN/TS 19101 on the application of the following informative annexes:

Annex A Annex B Annex E

The National Annex can contain, directly or by reference, non-contradictory complementary information

for ease of implementation, provided it does not alter any provisions of the Eurocodes.

1 Scope
1.1 Scope of FprCEN/TS 19101

(1) This document applies to the design of buildings, bridges and other civil engineering structures in

fibre-polymer composite materials, including permanent and temporary structures. It complies with the

principles and requirements for the safety, serviceability and durability of structures, the basis of their

design and verification that are given in EN 1990.

NOTE In this document, fibre-polymer composite materials are referred to as composite materials or as

composites.

(2) This document is only concerned with the requirements for resistance, serviceability, durability and

fire resistance of composite structures.
NOTE 1 Specific requirements concerning seismic design are not considered.

NOTE 2 Other requirements, e.g. concerning thermal or acoustic insulation, are not considered.

(3) This document gives a general basis for the design of composite structures composed of (i) composite

members, or (ii) combinations of composite members and members of other materials (hybrid-

composite structures), and (iii) the joints between these members.

(4) This document applies to composite structures in which the values of material temperature in

members, joints and components in service conditions are (i) higher than -40 °C and (ii) lower than

T - 20 °C, where T is the glass transition temperature of composite, core and adhesive materials, defined

g g
according to 5.1(1).

NOTE 1 Composite structures have a temperature-dependent behaviour. The temperature-dependence of the

properties of composite, core and adhesive materials is considered through a conversion factor for temperature,

, as defined in 4.4.7.2, which depends on the g and the maximum material temperature in service conditions

( ).

NOTE 2 5.1(1) defines requirements for the g of composite, core and adhesive materials as a function of the .

(5) This document applies to:
(i) composite members, i.e. profiles and sandwich panels, and
(ii) bolted, bonded and hybrid joints and their connections.

NOTE 1 Profiles and sandwich panels can be applied in structural systems such as beams, columns, frames,

trusses, slabs, plates and shells.

NOTE 2 Sandwich panels include homogenous core and web-core panels. In web-core panels, the cells between

webs can be filled (e.g. with foam) or remain empty (e.g. panels from pultruded profiles).

NOTE 3 This document does not apply to sandwich panels made of metallic face sheets.

NOTE 4 Built-up members can result from the assembly of two or more profiles, through bolting and/or adhesive

bonding.

NOTE 5 The main manufacturing processes of composite members include pultrusion, filament winding, hand

layup, resin transfer moulding (RTM), resin infusion moulding (RIM), vacuum-assisted resin transfer moulding

(VARTM).

NOTE 6 This document does not apply to composite cables or special types of civil engineering works (e.g.

pressure vessels, tanks or chemical storage containers).

FprCEN/TS 19101:2022 (E)
(6) This document applies to:

(i) the composite components of composite members, i.e. composite plies, composite laminates, sandwich

cores and plates or profiles, and

(ii) the components of joints or their connections, i.e. connection plates or profiles (e.g. cleats), bolts, and

adhesive layers.

NOTE 1 Composite components are composed of composite materials (i.e. fibres and matrix resins) and core

materials. Components of joints and their connections are also composed of composite, steel or adhesive materials.

NOTE 2 The fibre architecture of composite components can comprise a single type of fibres or a hybrid of two

or more types of fibres.

NOTE 3 This document does not apply to composite components used for internal reinforcement of concrete

structures (composite rebars) or strengthening of existing structures (composite rebars, strips or sheets).

(7) This document applies to composite materials, comprising:
(i) glass, carbon, basalt or aramid fibres, and

(ii) a matrix based on unsaturated polyester, vinylester, epoxy or phenolic thermoset resins.

NOTE This document does not apply to composite materials comprising a matrix based on thermoplastic

resins.

(8) This document applies to the core materials (i) polymeric foams, and (ii) balsa wood.

NOTE 1 The core of sandwich panels can be reinforced by composite webs and inserts.

NOTE 2 This document does not apply to honeycomb cores.

(9) This document applies to thermoset adhesives, including epoxy, polyurethane, and acrylic resins.

NOTE This document does not apply to thermoplastic adhesives.

(10) This document applies to other types of fibres, thermoset resins, homogeneous cores and thermoset

adhesives than those specified in 1.1(6)-(9), provided that their mechanical and physical properties are

obtained from appropriate testing according to Clause 5, and that they are in line with the other relevant

clauses of this document.
1.2 Assumptions
(1) The assumptions of EN 1990 apply to this document.

(2) This document is intended to be used in conjunction with EN 1990, EN 1991 (all parts), EN 1997 (all

parts), EN 1998 (all parts), ENs, EADs and ETAs for construction products relevant to composite

structures.
