A madeira lamelada colada (MLC) tem sido amplamente utilizada na construção civil devido à sua alta resistência e versatilidade. No entanto, sua ruptura sob flexão pode ser frágil, exigindo reforços estruturais para melhorar seu desempenho. Este artigo apresenta uma revisão da literatura sobre métodos de reforço de vigas de MLC, com foco no uso de polímeros reforçados com fibra (FRP). São abordadas as características da MLC, os principais materiais de reforço, as metodologias de inserção das barras e as modelagens numéricas aplicadas, incluindo o Método dos Elementos Finitos (MEF). Os estudos mostram que o reforço com FRP melhora a resistência e a rigidez das vigas, embora desafios como aderência e comportamento em situação de incêndio ainda exijam investigações futuras. A revisão destaca lacunas na literatura e sugere direções para otimização dos reforços, combinando abordagens experimentais e numéricas.
